Exercise and Testosterone Therapy in Elderly Men With Physical Frailty

January 22, 2018 updated by: Ellen F. Binder, MD, Washington University School of Medicine
The primary aim of this study is to determine, in hypogonadal older men with physical frailty, whether exercise training combined with testosterone replacement therapy can improve skeletal muscle strength, and lean mass, to a greater degree than exercise training alone.

Study Overview

Detailed Description

Decreases in physical abilities, including losses of strength, endurance, balance, and coordination are major causes of disability and loss of independence in older men. Such individuals are at high risk for injurious falls, hospitalization, and use of supportive services. Age-associated testosterone deficiency may contribute to deficits in muscle mass and strength that are common in this patient population.

The primary aim of this study is to determine, in hypogonadal older men with physical frailty, whether six months of exercise training combined with testosterone replacement therapy can improve skeletal muscle mass and skeletal muscle strength, to a greater degree than six months of exercise training alone.

Secondary study aims are to determine in hypogonadal older men with physical frailty, whether six months of exercise training combined with testosterone replacement therapy can improve physical function, bone mineral density, and quality of life, to a greater degree than six months of exercise training alone.

Comparison: Men age 65 years and older who meet criteria for physical frailty and have a serum testosterone level below 350 ng/dl are randomly assigned to one of two groups: 1) transdermal testosterone replacement therapy + supervised exercise training for six months vs. 2) inactive placebo gel + supervised exercise training for six months.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Transdermal Testosterone gel (1%)
Transdermal testosterone 1% gel (Androgel) provided as 2.5 gm and/or 5 gm gel packets with dose titration and monthly dose adjustments to achieve and maintain serum total testosterone level between 500-900 mg/dL. Gel to be applied daily by participants. Participants are blinded to the contents of the gel packets. Participants in this arm also perform supervised exercise training for 6 months.
Transdermal testosterone replacement therapy with Androgel(TM). Daily application of gel at 5 mg, 7.5 gm, or 10 gm for six months. Target serum total testosterone level between 500-900 ng/dl.
Other Names:
  • Androgel
Supervised exercise training performed on site at academic medical center exercise facility. Exercise training consisted of 2 months of flexibility, balance, treadmill walking, and physical therapy-type exercises, followed by 4 months of progressive resistance training.
Placebo Comparator: Placebo gel
Inactive topical gel identical in appearance to the active medication, provided in packets identical to the packaging for the active medication. Gel to be applied daily by participants. Participants are blinded to the contents of the gel packets. Participants in this arm also perform supervised exercise training for 6 months.
Supervised exercise training performed on site at academic medical center exercise facility. Exercise training consisted of 2 months of flexibility, balance, treadmill walking, and physical therapy-type exercises, followed by 4 months of progressive resistance training.

Change in Total Modified Physical Performance (mPPT) Score
Time Frame: Baseline and Six Months
The Modified Physical Performance Test (mPPT) is a direct observational test that assesses multiple dimensions of physical function (basic and complex activities of daily living [ADL]) with different levels of difficulty. The test consists of 9 performance tasks. The total score range is 0-36 (min-max), with higher scores indicating better performance. Sub-scores are assigned for each of 9 item tasks; sub-score range is 0-4 (min-max) with higher scores indicating better performance. The sub-scores are summed to compute the total score.
